Air Conditioning Primary Seals

The evolution from R12 to R134A air conditioning systems required a change to the air conditioning core specification. The new leak requirement and the assembly plant’s need for higher flow while charging made necessary a valve more robust than the original Schrader Pacific design. The resulting new Primary Seal valve assembly is a 100% leak-tested, multiple poke-yoked valve assembly designed to meet the high flow and leak integrity the industry demands. Schrader Pacific manufactures over 12 million primary seal valves each year, and achieves a zero-defect quality level. An estimated 250 million Schrader Pacific primary seal valves are currently used in air conditioning applications worldwide.

Schrader Pacific part numbers include: 7142810093, 7142820093 and 0123415001.

Note: Due to the variety of operating conditions or applications, the customer is responsible to perform their own testing to insure performance, safety and warning requirements for the intended application.
